memory_limit is set to a very high value. Are
you sure your apps require this much memory? If not, lower the limit, as certain attacks or poor
programming practices can lead to exhaustion of server resources. It is recommended that you set this
to a realistic value (8M for example) from which it can be expanded as required.

open_basedir is disabled. When
this is enabled, only files that are in the
given directory/directories and their subdirectories can be read by PHP scripts.
You should consider turning this on. Keep in mind that other web applications not
written in PHP will not be restricted by this setting.
